MySQL 支持资源组的创建和管理，并允许将服务器内运行的线程分配给特定组，使线程根据组可用的资源执行。本节介绍可用于资源组管理的 SQL 语句。关于资源组能力的一般讨论，请参见 第 7.1.16 节“资源组”。MySQL supports creation and management of resource groups, and permits assigning threads running within the server to particular groups so that threads execute according to the resources available to the group. This section describes the SQL statements available for resource group management. For general discussion of the resource group capability, see Section 7.1.16, “Resource Groups”.
